Where is the universe? Why does it exist? What is cause and effect? What is eternity?

The universe itself is an abstract concept, some people say that the universe is boundless, and some people say that the universe has a size, but this size cannot be measured and confirmed. In fact, we are a small part of the universe, and subjectively speaking, the universe is in our hearts, and what we know is our subjective judgment. And existence is reasonable, just like why there are flowers and birds in this world, and people have mountains, our existence is the miracle of this universe.

The so-called cause and effect are just the various implications between things. For example, when an event occurs, there must be a cause and effect. The theory of causal reincarnation is very popular now, but no one can say what it actually is, and sometimes, cause and effect is just a helpless summary of our world.

Speaking of eternity, I think nothing in this world is eternal, because there is life and death, and death represents the beginning. The beginning of a new life, can you say that it is the same as the previous life? The answer is obvious, it cannot be exactly the same, and the form and consciousness of life have changed to a greater or lesser extent.

If there is eternity in this world, it is what is firm in our hearts ...

..Hello, these can be produced in part with the current science. It's not clueless.

Let me start with two complex concepts.

The first one is the theory of relativity, don't be afraid, I'll tell you a simple one, for example, if you play with firecrackers, you pop and explode, you can hear sound waves, if it's stronger, like missiles, you can see very bright light, that's visible light, that's light waves, and then you can hear sound waves, and then then the sound waves are gone, but there's an echo, and so on.

Einstein's theory of relativity is to explain how the substance of the event is transformed by the sound of an object.

But it's all at the ionic level. For example, how much energy does a hydrogen atom absorb becomes a helium atom, how much energy does it release, how many photons do it release, and so on.

The second. Hubble Telescope.

And I think you've heard of the Hubble telescope, and the principle is very simple: when an object moves, there's always a front and back problem, and the stars in the universe move in front and back, and the forward side in the Hubble telescope is just a little red. It's just relatively blue, and it's relatively blue (the same goes for it.) Relatively, we can see if a star is moving away from us or approaching us.

Looking at the Hubble telescope, we found a very, very, very interesting phenomenon.

That is, all the stars are moving away from our earth.

This is the result of the expansion of the universe, and this is not a hypothesis, but a fact.

The conclusion that can be drawn from this fact is even more interesting.

That is, because the universe is expanding as a result. Tomorrow's universe is bigger than today's, and today's universe is bigger than yesterday's.

Yesterday's universe was bigger than yesterday's. n...You're going to take a day out of the universe without yesterday (the concept of time doesn't exist here, because this day is the birth day of the universe, and we call it the big day of the universe.) All the time starts from this point).

As for what's out there, you ask? I'm sorry. Scientists today are just looking at what's going on. That's not all.

And now that we have this philosophical reflection -- that the universe has a first day.

Then there's a legitimate question. Which day is the first day?

Scientists are using big ears (the same radar as the pot lid. When you listen to the waves in the universe, you always hear a murmur, a very stable murmur.

Later, after research by researchers in Princeton, it was discovered that this indelible noise was the echo produced by the universe.

And then we go through Einstein's theory of relativity to estimate the length of time for this echo.

And we get a result, and that's that today's universe was created 13.7 billion years ago

Tired. Let's fight so much first.

Hello. These are all questions that the scientific community cannot give convincing questions at present, only some possible but unimaginable hypotheses. For example, the cosmic hypothesis holds that the universe started from a black hole with nothing, and this cloud is constantly expanding.

This explanation makes it completely unimaginable to use the human perception of time and space ... No way.

Correspondingly, existence, cause and effect, and eternity are all concepts that are difficult to convey in this hypothesis.

Of course, there are other hypotheses, I've seen it before, and I think it's even more incomprehensible, and I can't remember the name...

In short, our minds must tolerate something that cannot yet be explained. You tell me.

If you want to be scientific, you can't. If I want to be philosophical, my short answer is as follows: Where is the universe **?

It's all around you. Why does it exist? It's because you exist.

What is cause and effect? Cause and effect are good and evil, because good and evil are rewarded. What is eternity?

Eternity is the soul and lasts forever.

The universe has always existed.

Cause and effect is the spirituality that only intelligent human beings have, and the relationship between things that is generalized by this spirituality.

Even if the universe is destroyed. There should also be other substances that exist in some form.

Cause and effect don't die out of this!

It's just that there is no life and wisdom, and no one speaks up.

There are many kinds of emptiness, such as breaking emptiness, evil emptiness, and even denying cause and effect, but we generally refer to prajna emptiness, such as human beings or all sentient beings, who come to the world for various causes, which is real, but once death turns into dirt and dust, there is nothing left, and this is prajna emptiness! I believe that even if the universe is destroyed, cause and effect must exist, but this cause and effect is not cause and effect, but it is called cause and effect!

First of all, it is necessary to clarify the meaning of emptiness, which has many meanings, depending on the specific context. One of them is the more esoteric pretence, which is more difficult to explain, and what needs to be perceived can also be realized through the heart and mind of the interpreter, such as the Buddha smiling at the Lingshan meeting, and the Buddha will smile. Emptiness here is an eternal existence that is everywhere, has nothing, but contains everything, like the field of physics or dark matter.

Another meaning of emptiness is relative to phase and color, phase and color are processes and phenomena, which are temporary and not eternal, and the phase and void are one, and the phase and emptiness coexist, that is, the so-called color is emptiness, and emptiness is color. The five aggregates are empty, and all the laws are empty, which is used as a verb or to describe the spring lifting word, which means to let go, not to be attached, not to produce thoughts.

Cause and effect are eternal, just like the laws of science, and are not subject to human will. The destruction of the universe also exists, the universe is multiple, the energy is eternal, the destruction of the universe means the birth of a new universe, emptiness is eternal, there is a law of things, that is, there is movement, there is cause and effect.

In addition to cause and effect, there are at least the following relationships between things.

First, the contradictory relationship, two things can not exist at the same time, there is you without me, there is me without you, the story of the legendary "spear and shield" is its classic elaboration.

Second, the relationship between the two things cannot not exist at the same time, one must exist.

Third, the transformation relation, under certain conditions, one thing can transform another thing.

Fourth, dependence, two things must work together in order for the bridge to work, such as the lock and the key, if the key is lost, the bright lead lock will lose its meaning; Without a lock, there will be nowhere to use the key.

Fifth, the relationship of opposites, the relationship of opposites is also the relationship of unity, if you don't understand, think again.

These relationships help us to understand the world outwardly, our own little universe internally, and help me to reveal all sorts of bizarre connections ...

Things always follow the established track of Zen, and the cause and effect of everything are in the Tao, and the so-called Tao is natural. And the Tao is from nothing to the Tao, there is the Tao in nothing, and the Tao socks are also nothing. The so-called unity of all laws means that the cause and effect of all things are established.

The Tao is connected, the Tao is round, the Tao is connected, endless, immortal and imperishable. All cause and effect are nothing, and all nothingness is the way. In the midst of the dust, we are the same people.

Cathartic. At present, the scientific perspective is unknown, but this phenomenon can exist, but most of the world we live in at present is due to cause and effect, so the universe we understand is cause and effect.

But! Most people forget this! That is, what determines the order of cause and effect?

Time! And time, just non-linear, the change of time is intermittent and there is no law to follow, that is to say, cause and effect do not follow a line, time may also be a circle, cause determines effect, and effect determines cause, the universe is large**.

After the expansion is completed, it collapses again and returns to the singularity, in **... It's all possible.

I suggest you read "Time".

This book, this book reasonably explains the problem raised by the landlord. Another thing to mention is about the movie "Arrival.

The heroine's description of the cause of time and effect is very factual and unique, which is why "Arrival" is called a hard science fiction movie, you can watch it if you are interested.

From a philosophical point of view, nothing is eternal, and things follow the universal law of development and fend for themselves.

From a physical and astronomical point of view, there is no such thing as an eternal object. For example, time, time is relative, it stops in a black hole. Another example is a star, it also has its development mechanism, although the time is long, but one day it will become a black hole or a white dwarf star or **.

Humans too, evolved from apes, are relatively highly civilized, but will one day perish.

Only gravity, magnetism, strong force, and weak force in the universe are eternal.

If we have to be eternal, there is only energy, because only energy is transformed (not only in our universe, but also in this universe and in other universes), and it is neither created nor disappeared.

Yes. Electromagnetic waves are eternal.

Your question is too broad, I think the universe is changing, and there is no such thing as eternal.

Eternal existence is called "existence". But it's not a thing, it's the source of something.

Is life on Earth the only one in the vast universe? Are there other lifeforms?

No, first of all, what is the definition of life, there is metabolism to reproduce and die that is called life. The energy and matter of the universe are finite, and if there is eternal and immortal life, then the energy and matter of the universe are not infinitely concentrated on it. Besides, why there have been no immortal species for hundreds of millions of years, because immortal species cannot adapt to the natural environment.
